OpenGL community,

Here are 8 videos demonstrating GPU-accelerated path rendering with the NV_path_rendering extensions for CUDA-capable GPUs:

elFarto,

> does it require some specific piece of functionality only found on NVIDIA's GPU?

Yes, NV_path_rendering requires your GPU to be CUDA-capable.

I added GL.PathCommandsNV(pathTemplate, 0, nil, 0, GL_FLOAT, nil) before and error is disappeared.
I guess, in SDK demo this line must be too, because after I added it, stroke width start look...

Very good question. Paths are a well-developed concept in resolution-independent 2D graphics. PostScript, PDF, SVG, Flash, TrueType, Quartz 2D, Cairo, Skia, XPS, etc. all have the concept. It...

Be happy then. NV_path_rendering uses the standard 4x4 modelview and projection matrices only with the viewport/depth-range transform.

I encourage you to look at the nvpr_tiger3d example in the ...

www.opengl.org,

Normally 3D rendering and high-quality, path-based 2D rendering are distinct forms of rendering that cannot easily be mixed. Moreover while the GPU excels at 3D rendering,...

I've gotten some emails asking how to download the slides for the "OpenGL 4 for 2010" NVIDIA sponsor session at SIGGRAPH that Barthold and I presented. You can get the (corrected & expanded) slides...

opengl.org,

Stenciled shadow volumes provide a GPU-accelerated basis for shadow determination. Learn from this SIGGRAPH 2004 presentation (newly salvaged from my bit-attic) how OpenGL features...

> If you are really _the_ Mark Kilgard, I have to say, I'm rather shocked by your suggestions. In one of your recent postings, you said that "The Beast has now 666 entry points". Do you really...

> As far as I know, display lists are deprecated or even removed in OpenGL 3.1.

This whole idea of deprecating removing features from OpenGL is just a really stupid idea. This is a great example...

Jan,

Can you include your vertex shader?

- Mark Kilgard, NVIDIA

OpenGL believers,

OpenGL 3.0 has exactly 666 entry points.

The end is near!

- Mark

The presence or absence of any particular hardware vendor is less notable than how numerous engineers at ISVs were ready and willing to contribute feedback and comments on the specification. It's...

C'omn, cut a guy a little slack. It sure felt like I was thinking while implementing.

The EXT_direct_state_access extension is easy to use.

Before after/examples:

// before DSA
glActiveTexture(GL_TEXTURE2);
glBindTexture(GL_TEXTURE_2D, texobj);
glEnable(GL_TEXTURE_2D);

Re: http://www.opengl.org/registry/specs/EXT/direct_state_access.txt

OpenGL extension specifications aren't generally contenders for the designation "funniest thing I've seen all day."

I'm...

Here's some advice for determining why a GLSL program might have failed on NVIDIA hardware.

You can download the free Cg Toolkit and use the cgc (cgc.exe for Windows) compiler to compile your GLSL...

I'm going to try to clear up a couple of mis-conceptions about non-power-of-two (NPOT) and rectangle textures:

* NVIDIA has supported the texture rectangle functionality in hardware since the...

Here's what the OpenGL specification (added with OpenGL 1.2) says what the GL_MAX_ELEMENTS_VERTICES and GL_MAX_ELEMENT_INDICES limits for glDrawRangeElements mean:

opengl.org,

My slides from my SIGGRAPH 2006 presentation at Marc Olano's GPU Shading and Rendering course are now available on the NVIDIA Developer web site . See:

OpenGL has a specular, I mean bright, future.

NVIDIA has made a rock-solid commitment to OpenGL and I've been amazingly fortunate to participate in that commitment. NVIDIA's OpenGL driver is the...

A few more corrections:

Some OpenGL 2.0 specification nits for fixing in OpenGL 2.1:

The EXT_paletted_texture and EXT_shared_texture_palette extension specifications have documented for a while now that future NVIDIA GPUs would not support these extensions. See the Support section...
